The API tends to be unstable and often fail with a 500,
which makes the plugin disappear. Keeping a cache allows
to prevent some flickering of the graph.
This allows us to further split config data-fetching from live
data-fetching, thus removing the need to support DIRTYCONFIG.

We need to set the date for all plugins, otherwise the lagging `daily`
one is assumed for all, and confuses spoolfetch and other time-based
sanity checks.

Also make the daily graph more flexible, by always reporting the second
last value (presumably the previous, but sometimes the API lags a bit,
and actively requesting by date result in never reporting some late
data).
